Hi EE,

I have a problem with one of my servers not replicating to an OFF-SITE location. I am able to replicate ON-SITE to the same host without a problem or even to another host in the same environment. Replicating via VPN to our data center give me the following error

"processing configuration Error: The operation is not allowed in the current state."

I would like to add that I am able to replicate a different server from a different location to this same host without any problems via VPN.

Thanks

Setup: Laptop connected to our network via public WiFi over a VPN encrypted connection.

Trying to map a network drive so laptop user can save files to the server.

This worked one time:
net use k: \\xxx.xxx.xxx.xxx\transfer /u:
Prompted me for my username and password and mapped the drive

Subsequent attempts after rebooting yields a System error 53 network path was not found.

If I do the same command less the /u: parameter it maps the drive just fine but of course I cant get into the drive because of permission issues.

The username on the laptop is not the same as what the user would use if they were on site and actually logging into our network thus the reason for the /u switch.

Hello,

SonicWALL NSA routers

I have a network with 10 site to site vpn's. We switched providers on two of our sites. The buildings are on the same street and I got these IP's

Site A -   X.X.49.53
Site B -  X.X.49.52

I was able to recreate all of the tunnels with the exception of Site A to Site B. I'm wondering if it has to do with the fact that they are on the same .49 network. Any idea if this is the case?

Thanks in advanced

Client is looking to have 3 separate locations connect to FileMaker databases.  Sometimes 2 users will want to access the same file.

Can they set up FileMaker Pro on a Virtual Private Server and use that copy to serve files?   What is the limit of open files for non-server FileMaker at the moment?
IF they purchased FileMaker Server, would that work?

Could they remotely run FileMaker on a VPS?

Is there a way to do this?

Thanks.

We were issued a new modem by our ISP = ARRIS NVG443B.  Since then our remote office could not VPN into us.  I thought maybe our static IP had changed and ISP failed to tell us.  They say not - that our static IP is still the same.  I logged into new router and saw WAN IP as one number and what was our old IP down on the DHCP/LAN page listed as PRIVATE.  If we use the WAN IP in the VPN connect, it works and we get fully connected.  If we use our old static IP it always fails.  The ISP says that every time we VPN in using the WAN IP, it disconnects wireless service at the site.  That we should not be using the WAN IP....  I'm at a loss.  Anyone know how to properly configure the modem for VPN access?  Thanks in advance.

Hello:

i would like to export the settings from the Cisco RV120W firewall and then import them into a new Cisco RV130W Wireless-N Multifunction VPN Router.

Can this be done  and if so, can someone forward any instructions or links.

Thanks

Hi all,

We have a setup, where all computers are connected to the Head Office WSUS server so that we have a better visibility of all computers and we control which updates need to be downloaded.

Some of the computers are at our remote sites (connected via VPN) and we would like to reduce the bandwidth. Thus, we were thinking of having a physical server at our remote site which downloads the updates that we at the Head Office authorise and the clients download from the local WSUS site server.

The administrator still needs to control everything from the Head Office and authorise updates from 1 location (HO).

Thanks.

We have a Cisco RV320 dual wan vpn router. The first static public ip assigned to WAN1 let's say is a.a.a.a and WAN2 is b.b.b.b.  Each is from different ISP's have been tested by them and by me to be operational.  We have a site to site VPN in place using the ip a.a.a.a and the Cisco is in basic failover mode with WAN1 being the primary. The VPN is connected and operational.  The issue is this:

I want to use WAN2 for the vpn connection because it is much faster but when I switch the Primary WAN to WAN2 and change the tunnel to use WAN2 and change the peer address on the other site to point to the public ip on WAN2, the remote site does not connect to WAN2, I can't even ping it.

any help would be appreciated.

PS. I know the WAN2 address does indeed work because if I temporarily install another cheap router for testing and assign it that address, I can ping it no problem.

I have an Advanced Tomato Router with 2 WAN connections.
I want both WAN connections to be active, but only 1 of them to use the VPN (in and out).
Currently it seems to be a bit random as to which WAN the VPN connects through....

I assume it requires some custom IP stable scripts, but im not sure what to use....

Any advise would be great!

Thanks

I am new to  ASA firewall concept, I would like to know that  ASA firwall works  based on interface name or IP address, for an example if the traffic comes from outside(internet), and if we want all traffic to (inside) office network, do we need to say any IP address within specific range goes to inside interface ?  For an example how do we allow VPN traffic through firewall?

Dear Experts,

I have a user which started to have an issue with opening ppt files this week over vpn.
The strange thing is it's only happening with ppt files, pptx are opening fine.
If I copy the ppt file from the Shared drive to the desktop it takes 3-4 Seconds to copy and around 10 seconds to open.
If I open the same ppt file directly from a network share it takes around 3-4 Minutes to open or Powerpoint is even crashing.
The same files are opening fast when on the Office network.
I'm running out of ideas what could be the issue.
I tried the following until now:

- repair office
- Adjust MTU of the Wifi adapter
- start Powerpoint in safe mode
- disable all Add-ins
- Add network share in the trust center to trusted locations (including subfolders)

It's still the same after all this.

the following is used:
- Windows 7 64 Bit
- Office 2013
- Cisco Anyconnect

Best Regards and many thanks in advance for any input,

Patrick

I have a client application that connects to a SQL Server through a Fortigate FW VPN Tunnel at a remote office. The users can connect to the server/database with no problem, but if they leave the application for anywhere between 20 mins to an hour, the connection will timeout and they'll start receiving connection errors, etc. Once they log back in, they are fine. We have other remote offices that dont have this problem, and they all connect through the same type of Fortigate FW configured all the same. I've contacted the application vendor's support folks, and they say that the application is set the way it is supposed to be, and when I contact Fortigate, they cant find any reason for the timeouts.

What are some ideas that I should look at? I thought about the SQL Server, but if other offices are not having problems, then it would probably not be that. Any ideas would help, Im spinning my wheels at this point.

For info purposes the application is "Elite Enterprise" and that connects to the SQL Server.

Thanks in advance for the help!

Hi,



Can anyone help in identifying why once my vpn client enabled. I can  ping all other internal IPs except 192.168.4.1(interface DatabaseZone)  and 192.168.3.1. My vpn client assigned 192.168.5.100 which is in  the range ov VpHi,

So I've been tasked with creating an IPSec VPN using a Cisco RV325. I've followed through several guides to get this setup and as it currently stands, I've managed to create the tunnel, connect and authenticate to the VPN successfully using the Shrewsoft VPN Client. However, once connected with either the IPSec VPN or the EasyVPN, I am able to ping the internal address of the router, but unable to ping any other device on the remote LAN. I've made sure firewalls are turned off for testing purposes just to ensure the packets aren't being blocked. I've also tried RDP connections to devices with no joy.

Interestingly, when I tried using the PPTP VPN through the RV325 (using windows 'connect to a network') I'm able to ping everything and remote access servers etc.

I've noticed that the RV325 will give you a virtual IP address range (which the VPN client is picking up) although it seems like there's no kind of address translation or routing to the subnet I need to get to. My remote LAN uses 172.16.8.x/24, the virtual addresses use 172.16.9.x/24.

Please let me know if any log files, config files or screenshots of anything would be of any troubleshooting help and I'll get them posted. Any ideas welcome!

Many thanks in advanced,
Luke

I'm having a problem trying to remote desktop, with very specific circumstances. With all my HP Probook 430's and 450's, running Windows 7 Professional 64-bit. When they're outside of the domain at a remote site, connected successfully via VPN, they're supposed to be able to remote desktop to various computers inside our domain at our main site. But they can't. Instead I get the general error (attached). But none of the problems in the error are true.

Here are the odd circumstances. I have other machines - HP desktops, other laptops, etc. that can remote in via the same connection from the same remote site. So I know the connection is fine and I know our server-side VPN/firewall is fine. But also, these same HP laptops can remote connect to the target systems just fine when they're inside the domain at the home site. So their remote desktop connection software on the laptops is working fine. But something changes when those laptops go offsite that prevents them from connecting, and I can't tell what it is.

I've tried enabling and disabling the firewall on the laptops, but nothing's changed. I've tried disabling Symantec Endpoint Protection as well. I've also tried using the local admin login instead of the domain AD account login. Nothing's affected the issue.

Any ideas where to go from here?

We would like to set up a WSUS server in our DMZ (Internet Facing) for our external users to get MS updates.  I believe for licensing (EULA) requirements the users would have to vpn into the network to get the approved updates.
This would be managed separately from our internal WSUS server, so we don't need to 'downstream' updates from the DMZ  WSUS server to our internal WSUS server.
Server:  Windows 2016 Std, WSUS v 10.
Any suggested links, information, certificate requirements, etc., would be greatly appreciated.

Thank you,

Hey guys,

I´m troubleshooting very interesting issue...we have a branch connected over IPsec (setup on Mikrotik)...everything works pretty much fine but network drivers...when users wants to open it it takes very long time to open it approx 5 mins...if they connect over VPN everything is fine. Any ideas? We use 3des encryption for IPsec

Thank you very much!!

Regards

I have several Cisco 881 deployed in the field for VPN connectivity back to my main office.   When the ASA at the main office gets rebooted during routine maintenance, the Cisco 881 always have to be rebooted before they will re-establish a VPN connection.   Is there anything I can put in the config, that would allow the Cisco 881's to auto reconnect after the ASA has been rebooted?   Below is a copy of one of the configs.  Thanks in advance.
